About Nestoritherium
Nestoritherium is an extinct genus of chalicothere; it has been dated to have lived from the late Miocene to the Early Pleistocene (11.6–0.781 mya). This range makes Nestoritherium one of the most recently dated chalicotheres. It has been found in fossil sites in India(Pinjor Formation), Indonesia, Myanmar and China.
The genus Nestoritherium was erected by German paleontologist Johann Jakob Kaup in 1859 for the species then known as Chalicotherium sivalense, itself named in 1843 by Falconer and Cautley from early Pleistocene material from India, that were collected from the region west of Yamuna alongside Giraffa sivalensis, Sivatherium, Camelus sivalensis, and numerous others. Later in 1868, a nearly complete anterior portion of the skull from the Dadoopoor collection of Messrs, Baker and Durand(which was most likely collected from Dadupur, Haryana of northern India), was referred to Nestoritherium sivalense. Robert Hardwicke, London The shortened faced and brachyodont dentition suggests it belongs to the subfamily Chalicotheriinae.
Nestoritherium fuguense was named from partial lower jaw and palate material from Miocene beds in Fugu County, China in 2014.
